Someone is DDoSing vx-underground.

This is terrible news. I was going to work on the website, but now all I can do is spend time with my family and enjoy a beautiful summer day

Terrible, this is just plain terrible

Welp, do your thing big dawg, hit me up when you're done

Hi

More malware has been uploaded to VXUG. It's like, 150,000 malwares, or something. I also uploaded more malware analysis papers.

Show it to your parents, they'll be proud of you.

I am filled with disappointment.

Last time on Dragon Ball Z, I announced my boredom with malware development, hence I decided to pivot to malware defense. I began by taking apart YARA to understand how it works, and making my own little silly YARA scanner. Whatever.

I then began reviewing the malware people discovered in the wild. I have reviewed hundreds of malwares, and many also non-malwares.

Unfortunately, I am at the point where I am no longer finding original goop. It is the same malware campaigns, different person sending it, different compromised webhosts, or slightly tweaked SHA256 hashes.

I now feel the existential dread my blue team colleagues feel. It is the same gunk everyday. The gunk is persistent. The gunk is infinite and vast. The gunk is like an ocean of gunk.

"What if we used AI to turn source code into a binary?"

Lots of stuff happening with vx-underground at DEFCON

It's all very confusing though because I don't go to conferences, and many of the vx-underground things occurring I was not informed of, or made aware of, or I literally don't even know what it is

So it's just kind of weird when I'm chilling and I'm notified like, VXUNDERGROUND THING HAPPENING AT DEFCON and I just stare at my screen like ?????

Then people message me if I'm at DEFCON and I'm like "nah" and then they're like "omg thank you so much for the goop" and they send me a picture of something I've never seen before, or a picture of someone I've never met in my entire life

I don't care, I just do malware stuff and collect pictures of cats, but it's all very confusing and it hurts my little brain because I don't go outside but apparently I (or my crappy project) is doing many things that I myself didn't know existed

Anyway, yeah I have no idea what's going on, I'm not there, I'm sniffing around the internet looking for goop

Them: "Great meeting you at DEFCON! Thanks for the stuff!"
Then: *Sends picture of people and stuff*

Me:
- I'm not there
- I don't know who you are
- I didn't give you anything
- I don't know what you got
- I don't know the people in the photo

Me: "No problem, bro" (I don't know what's going on)

dude, what in the fuck is this shit?

.vbs -> .zip -> .msi (files 1 - 6)

.msi_file6 -> msi_file4

.msi_file4 -> autoitscript

autoitscript -> .exe

.exe -> msi_file5

these nerds put in a significant amount of effort to make this as multi-staged and as convoluted as possible. this is 100% AI generated. they left the notes in place. however, based on everything i'm seeing, i think this person probably has a decent understanding of malware and understands how annoying this is

tl;dr not super sophisticated malware, but really fucking annoying

oh, and the files arent on VT, for my colleagues who care about weird annoying goop

Had a dream last night about malware

Outside doing family stuff, daydreaming of my malware idea. Super excited to sit down on computer and bonk malware.

God I love malware so much

my idea failed

I've had so many people talk to me about looking for entry level material for malware, I've decided to give writing a book another try.

I'm going to call it "Malware for Noobs" and just schizo rant a bunch on my blog until I think it's enough for a book

Maybe someone will pick it up and I can have it published at a fancy place like Barnes and Noble, then I can be called cool and badass and people can make fun of me

Some dork on Instagram is accusing me of being behind the whole Mecca Chameleon steam malware thingie and says @IntCyberDigest labeled me the criminal, or something, I don't know.

I'm not even mad they called me a criminal, I'm mad they would accuse me of making weak malware.

I've got a family now, I'm basically a born again Christian, I drive the speed limit, wear socks with sandals, and tuck my shirt into my cargo shorts. I don't do anything even close to illegal.

However, if I was going to switch it up and become a full fledged Threat Actor, I am NOT going to do something half-baked like this Mecca Chameleon thing, I'm going to develop an information stealer, partially AI generated, written in like five different programming languages, and storing the payload on something goofy like a Billie Eilish instagram comment. Then I am going to sell it online on some place like Tier1 and deal strictly in XMR.

I am insulted you would think I would stoop so low to do something like a malicious Steam game (or hijack).
